Question: Explain the difference between hibernation and torpor. Answer: Hibernation and torpor are both survival strategies used by animals to conserve energy during challenging environmental conditions, involving periods of inactivity and slowed metabolic processes. The main differences between the two lie in their duration and intensity. Hibernation is a long-term strategy that lasts for weeks to months, with a more significant decrease in body temperature and metabolic processes. In contrast, torpor is a short-term strategy that lasts for hours to days, with less dramatic reductions in body temperature and metabolic function. Examples of hibernating animals include bears, ground squirrels, and bats, while animals that undergo torpor include hummingbirds, skunks, and some species of mice.
